Bastion hosts often act as gatekeepers for accessing critical infrastructure, but managing their security and usability can become a burden for engineering teams. Especially when it comes to on-call responsibilities, you need fast, secure access without the bottlenecks of traditional bastion setups. Let’s explore how to replace bastion hosts and streamline engineer access for on-call operations.
What's Wrong with Traditional Bastion Hosts?
Bastion hosts were designed as a central point to manage access to servers. While useful in theory, they often introduce more problems than they solve:
- Manual Key Management: Engineers need to distribute and maintain SSH keys or credentials. This creates friction, especially when roles change or new team members join.
- Limited Auditing: Logs from bastion hosts need to be aggregated and analyzed manually, making it difficult to trace access events reliably.
- Single Point of Failure: If the bastion host goes down, all server access may halt until it’s resolved.
- Operational Overhead: Managing, updating, and securing bastion hosts consume valuable engineering time.
As on-call dynamics demand quick problem resolution, these inefficiencies become even more pronounced.
A Modern Approach to Secure Access for On-Call Engineers
Replacing a bastion host involves eliminating SSH-based access and adopting a modern, zero-trust access model. With this approach, engineers can securely gain access without the operational baggage of bastion hosts. Here are the key components of a replacement strategy:
1. Identity-Based Access
Switch from managing static keys to using your company’s existing identity provider (IdP). Popular IdPs like Okta, Google Workspace, or Azure AD can ensure that only authorized users gain access, based on real-time roles and policies. Integration with your IdP ensures automatic offboarding and role adjustments.
2. Temporary Credentials
Instead of permanent credentials, use temporary, time-limited tokens for server access. This avoids the risks of leaked credentials while ensuring that engineers never have unrestricted access outside of their active session.
3. Centralized Access Control
Adopt a tool that centralizes access governance, giving managers visibility into who accessed what, when, and how. Granular auditing makes compliance and troubleshooting easier, something bastion hosts typically struggle to provide.
4. Direct-to-Service Connections
Remove public-facing SSH altogether. Modern access tools can enable secure, proxied connections to private infrastructure using encrypted tunnels. This eliminates the need for a single choke point like a bastion host.
Why It Matters for On-Call Workflows
On-call work requires engineers to respond to incidents fast. Navigating through outdated bastion host setups slows them down and increases stress during critical events. Simplifying access provides multiple benefits:
- Faster Resolution: Engineers can connect directly to affected systems in seconds.
- Improved Security: Temporary credentials reduce attack surface and mitigate risks of unauthorized access.
- Simplified Management: With centralized access, policies can be applied consistently across all environments without managing individual bastion hosts.
- Better Audit Trails: Detailed activity logs make compliance easier and let you detect anomalies sooner.
Replacing bastion hosts isn’t just about cutting operational overhead—it’s about enabling a more secure and efficient way for your team to operate under pressure.
